Abstract

Dispositif pour la reproduction de signaux vidéo à différentes vitesses. Le dispositif comprend une bande sur laquelle est enregistré un signal vidéo sur des voies contiguës et inclinées par rapport à la direction longitudinale de la bande, voies enregistrées par plusieurs têtes tournantes présentant des angles d'azimuth différents. Il comprend également des organes pour faire avancer la bande à une vitesse V = V0 (n +- 2)/n, V0 représentant la vitesse d'avance normale et n étant un entier positif. Application à la reproduction de signaux vidéo à des vitesses différentes de celle à laquelle ils ont été enregistrés, à savoir supérieures ou inférieures à celle-ci ainsi qu'à la reproduction dite arrêt sur image.Device for the reproduction of video signals at different speeds. The device comprises a tape on which is recorded a video signal on contiguous tracks and inclined with respect to the longitudinal direction of the tape, tracks recorded by several rotating heads having different azimuth angles. It also includes members for advancing the strip at a speed V = V0 (n + - 2) / n, V0 representing the normal speed of advance and n being a positive integer. Application to the reproduction of video signals at speeds different from that at which they were recorded, namely higher or lower than the latter, as well as to the so-called freeze-frame reproduction.
